Koopmeiners has invited attraction from multiple clubs this summer thanks to his exploits this season with Atalanta in Serie A. As such, the Red Devils have shown interest in the 26-year-old Dutchman, with co-owner Sir Jim Ratcliffe looking to overhaul the dressing room; Casemiro, Christian Eriksen and Donny van de Beek could all depart, leaving room in midfield for Koopmeiners. As per Calciomercato, United would be ready to pay around €60 million (£51m/$64.8m).
